Thanks! However, I think that it would be better to mention that it is
fine to use a different value -- instead of discouraging them.

This doesn't help for the common case of ssh. (In fact, this was what I
originally though about using, but configuring ssh/sshd to pass
INSIDE_EMACS is a PITA to manage.) I'm not saying that it shouldn't be
mentioned, just that it's not too helpful...

Thanks -- you can verify this with the wiki page too at:
https://www.emacswiki.org/emacs/TrampMode
where I added the "tramp" solution.

But this is exactly the problem: "dumb" is used in many contexts,
including in `M-x shell`. This means that if I follow what you're
recommending, I end up with a crippled `M-x shell` experience since I
lose my useful prompt there. OTOH, I can't imagine that anything that
tramp uses would rely on terminfo, which is why I suggested the above.
